he's made nominal progress, but that's about it. there are still a huge number of possessions where the balls never touches anybody's hands except al and the initiator on the strong side wing for most/all of the shot clock. and here's the thing... even if he scores on that play, it's just not good basketball. he's an elite post scorer, but the effect he has on team execution is negative. he uses 22.5 possessions per 40 minutes -- or about 28.6% of the team's possessions -- plus all the ones where he doesn't officially use the play but he dictates what happens because he stops the ball so long that by the time he finally gets rid of it there isn't time to go through the set and run the options so someone winds up shooting a late inefficient shot.
now consider that he gets 1.04 points per shot, or .974 points per possession... both below the team average. why would you let a player that inefficient dictate somewhere around a third of your team's offense?
final thought: if, as a previous poster stated, al/fav/kan are "interchangeable" then isn't keeping all 3 a bad idea? don't you need some versatility? if you have three guys who are a little too undistinguishable, aren't you a ridiculously easy team to prep for and shut down? not to mention that miami just showed the league how to shut down al: front him, ball-deny and, if it comes right down to it, just put a smaller hyperactive defender on him to frustrate him because he doesn't play physical enough to use his size advantage to overpower anybody.
